Hi. Personally, I would not trust an "ISP" based NTP server! From personal experience, they tend to run them on the heavily congested border/gateway systems. As you can find and confirm using the usual network routing and diagnostic tools.
As has been said, local GPS / Internet sync'd servers would be best, and easy to setup and maintain. The fun bit will probably be the management arguments about running one (or hopefully more) GPS receivers, and the associated cables in from the outside.. Don't forget to run them from a UPS!.. If you end up with more than one local server, and there are more than one UPS protected power sources, spread the load around and add redundancy. All that can be done on a "shoestring" and still give good quality service. Or you could raise some funds, and purchase two or three of these:- http://www.leobodnar.com/shop/index.php?main_page=product_info&cPath=120&products_id=272 No affiliation, but they come recommended. (And I've only just noticed that they are not far from me.) Regards. Dave B.
